Description
Technical Field
the invention relates to the technical field of voice coil motors, in particular to a reed damping structure of a voice coil motor for rapid focusing of a camera.
Background
Because Voice Coil Motor (VCM) has simple structure, small, low energy consumption, noiselessness, high acceleration, response speed are fast, the displacement is accurate and advantage such as low price, so to camera automatic focusing device at present, Voice Coil Motor structure automatic focusing still is the highest mode of price/performance ratio. The optical lens is fixed on a voice coil motor carrier coil frame, the carrier is used as a power unit for lens movement, the voice coil motor carrier coil frame is connected with a stator through a reed, and the stator is formed by bonding or welding an upper shell and a base through glue. When the motor is powered on, the carrier wire frame moves linearly along the optical axis direction of the lens, and the shell and the base on the upper part of the stator respectively limit the carrier wire frame to move to the maximum displacement along the optical axis direction, so that the automatic focusing function is realized. The reed is used for balancing the electromagnetic force in the voice coil motor, so that the aim of accurately focusing is fulfilled through the balance of the elastic force, the gravity and the electromagnetic force.
at present, the thinner the existing mobile phone is, the smaller the space of the devices which can be arranged inside the mobile phone is, the problem can be caused, the arrangement between the vibration motor of the mobile phone and the voice coil motor which can automatically focus is very close, when the vibration motor vibrates, the energy can be transmitted to the voice coil motor through the shell of the mobile phone, the reed inside the voice coil motor drives the lens carrier to carry out damping vibration together, resonance can occur, and the situation that the shooting is fuzzy when the mobile phone vibrates is caused.
SUMMERY OF THE UTILITY MODEL
When vibrating in order to solve the vibrating motor in the cell-phone, the inside reed of voice coil motor is driving the carrier and is carrying out damping vibration jointly and the problem of resonance appears, the utility model aims at providing a reed shock-absorbing structure for voice coil motor.
The technical scheme adopted for realizing the aim of the utility model is as follows:
A reed damping structure for a voice coil motor, comprising: the spring comprises an iron shell, a reed, damping glue, a slow-energy elastic wire structure and an elastic wire structure; a reed is arranged in the iron shell; the reed is provided with damping glue; the reed is provided with a slow-energy spring wire structure and an elastic spring wire structure.
The utility model has the advantages that:
Through inciting somebody to action the utility model discloses a reed shock-absorbing structure for voice coil motor, when voice coil motor's damping structure part was sent out the vibration because cell-phone vibrating motor vibrates, the kinetic energy of carrier and reed part can be timely through elasticity bullet silk structure with energy transfer for damping glue, again with energy transfer for slow energy bullet silk and then with energy release outside iron-clad on, the carrier drives the lens section of thick bamboo part can the rapid stabilization get off like this for the quality of shooing promotes greatly.

Detailed Description
the present invention will be described in further detail with reference to the accompanying drawings 1-4 and the reference numerals.
A reed damping structure for a voice coil motor, comprising: the spring comprises an iron shell 1, a reed 2, damping glue 3, a slow-energy elastic wire structure 4 and an elastic wire structure 5; a reed 2 is arranged in the iron shell 1; the reed 2 is provided with damping glue 3; the reed 2 is provided with a slow elastic wire structure 4 and an elastic wire structure 5.
The outer frame of the reed 2 is provided with a slow spring wire structure 4 in a stamping mode, and the slow spring wire structure 4 is a ruler structure and is provided with four.
the inner frame 8 of the reed 2 is provided with four elastic thread structures 5 in a stamping mode, and the elastic thread structures 5 are arc-shaped structures.
Step surfaces for bonding and fixing are reserved at four corners of the iron shell 1, and the frame of the reed 2 is bonded and fixed with the step surfaces of the iron shell 1.
The outer frame 7 of the reed 2 is a fixed part, and a slow elastic wire structure 4 is led out from the outer frame; the spring leaf provides the elastic wire structure 5 of elasticity as the moving part; the slow-energy elastic wire structure 4 and the elastic wire structure 5 are arranged together to form a damping structure of the reed together.
A voice coil motor is with the release of the carrier kinetic energy of the realization through damping glue 3 between the slow energy bullet silk structure 4 that contains on the reed 2 that contains special construction and be connected with the reed outline and the elasticity bullet silk structure 5 that is connected with interior border.
Examples
A reed damping structure for a voice coil motor includes: an iron shell 1; a reed 2; a damping glue 3 for a voice coil motor. After the reed 2 is placed in the iron shell 1, the reed 2 is fixed on the four-corner fixing boss 6 of the iron shell 1 in a bonding mode. The inner frame 8 part of the reed 2 is used as a movable part, and the outer frame 7 of the special structure reed 2 is used as a fixed part. And then coating the damping glue 3 on the reed 2 containing the special structure, so that the inner frame 8 and the outer frame 7 of the reed 2 containing the special structure are connected through the damping glue 3. When voice coil motor received vibrating motor's influence, voice coil motor's inside damping structure can be along with vibrating from top to bottom, and the kinetic energy of camera lens carrier can transmit damping glue 3 through reed inside casing 8 this moment on, damping glue 3 transmits the ability bullet silk structure 4 again, on transmitting reed frame 7, releases the energy through iron-clad 1 at last.
Part of the kinetic energy of the carrier and the elastic potential energy of the reed is transmitted to the damping glue 3 through the elastic spring wire structure 5, then transmitted to the energy-buffering spring wire structure 4 and finally transmitted out through the iron shell 1; the other part of energy moves through the damping glue 3 and the energy-buffering elastic wire structure 5, and the kinetic energy of a part of carriers is converted into internal energy. So that the carrier can be rapidly stabilized.
